Thanks for the review. Curious how you found the Leupold bx4 compared to the viper, optically that is?I just had the following 10x42s side by side outside for a comparison. The Vipers, Zeiss Terras, Nikon Monarch 7s, Leupold BX4s.
The Nikons were a surprise. I liked the clarity and brightness a lot. But felt the focus wheel was a bit sloppy and was unsure on customer service. Regarding the Leupolds....dual bridge designs don't feel comfortable in my hands. The glass, diopter adjustment, and focus wheel felt good with good range of motion.
That left me to choose between the Vipers and Terras. The glass on the Terras was very good IMO. Clarity, sharpness, and brightness all were a step up that the Leupolds Im replacing. The Vipers were about the same but I felt the color/whites "popped" a little more than the Terras. Ive had this expierence before looking through Vortex optics. The image always seem to pop more to my eyes, even compared to my NF scopes.
I ended up with the Vipers. It was a tough call, but the performance between them all was so close. It came down to how they all felt in my hands, how much travel the focus wheels had, and warranty.
Once I settled don the Vipers I decided to compare them to the Razors and Zeiss Conquests. Jumping from $500 to $1000 glass made a difference. The Razors were shockingly light to hold which I liked. The glass on the Conquests was fantastic. If I had an extra $500 laying around I think I would of ended up with those.
